CE outflow

Initial condition: from Orsola's SPH result.

Boundary condition: a spherically symmetric outflow set at r=156R_sun, the outflow density is 5e-11 g/cc, outflow speed ram from 10km/s to 1000km/s. The duration of the 1000km/s outflow is from time=1day to time=40day. The mass loss rate is 1e-1 solar mass per year and the total mass loss is about 1e-2 solar mass. I have also added a 2 solar mass object at the center of the outflow.

Simulation: I use gamma=1.667 in this simulation. The maximum temperature during the late simulation is about 5e7 Kelvin which is unphysical. That high temperature happens at low density region where the shock heating is strong. I use 120 cores for 25 hours, that is 3000 CPU hours. It is static mesh refinement.
